Calibrating Printing Editing
Updated 04 March 2023.
THEORY
A brief summary from my Understanding Pictures workshop covering those pictorial design questions that also get asked in many of my other workshops – from Digital Printing to our Photoshop Master Class. Last updated 27 July 2020.
Notes from 1980 on the contribution of subjects-that-matter, structures, luminosity, and foundations on a print’s emanating presence. Last updated 24 May 2014.
APPLICATION
A link to our YouTube Channel and video introduction to 3DLUT Creator. Though this brief look at 3DLUT Creator ‘barely scratches the surface’ of its immense possibilities, profoundly creative controls, and stunning originality, I hope it nevertheless intrigues and encourages you to explore this utterly remarkable application. Last updated 21 November 2018.
Summarises approaches to localised image editing (selections, masks, and nodes) and 3DLUT Creator’s extraordinary facility of grid and curve nodes, along with the fundamental tasks of selecting, pinning and editing nodes with workflow shortcuts and processing priorities. Last updated 13 December 2020.
My original Live Picture workshop notes. Live Picture is a resolution independent real-time imaging program that runs under the Macintosh Classic operating system. Though Live Picture was commercially discontinued in December 1999 I continue to use it as one of my primary image editing programs. Last updated 28 November 2005.
A brief summary of the issues Photoshop imposes on a contemporary workflow and how Affinity Photo has eloquently addressed and resolved them, including encoding errors, thereby becoming the ‘Photoshop’ I had always wished for. Last updated 28 June 2021
PRACTICE
A simple outline of two basic evaluations anyone can undertake to help them understand why their prints do not match their screen and why Adobe Photoshop or Lightroom soft proofing does not work. Last updated 28 July 2019.
A collection of recommendations and observations on the digitising of cultural and biological collections, including quality control, verification, camera alignment, lighting, diffraction, and depth of field considerations. Last updated 03 December 2018.
The conversion of multi-channel images to a single greyscale channel is based on a luminosity formula, which in turn is based on a theory of perception. This paper examines Photoshop’s methodology and why desaturation and other conversion formulae do not always produce a satisfactory perceptual result. Last updated 24 May 2014.</em
A method for the local perceptual compression of Relative Colorimetric (B2A1) ‘out-of-gamut’ transformations using the L*a*b* colour model, as implemented in applications like Adobe Photoshop and analytical tools like ColorThink Pro. Last updated 11 December 2006.
The calculation of digital equivalents to Kodak’s Wratten Filters and their implementation in preparing digital BW fine prints. Last updated 13 June 2020.
A luminosity masking method for toning digital images so as to emulate the ‘look, feel and presence’ of toned silver gelatin fine prints. Last updated 03 August 2015.
